Iridoid glycosides from Lonicera quinquelocularis

Phytochemistry, 2000
A new iridoid glycoside 6'-O-beta-apiofuranosylsweroside was isolated from the ethanolic extract of the roots of Lonicera quinquelocularis along with the known compounds loganin and sweroside.

Iridoid Glycoside Constituents of Stachys lanata

Journal of Natural Products, 2008
From the aerial parts and roots of Stachys lanata, four new iridoid glucosides, stachysosides E-H (1-4), were isolated together with 30 known compounds. The structures and the stereo configurations of these new compounds were elucidated on the basis of the results of spectroscopic analysis. Compounds 1-4 are esters of monomelittoside.

Phenylpropanoid and iridoid glycosides fromPedicularis lasiophrys

Phytochemistry, 1992
Two new compounds, pedicularioside E and F, were isolated from whole plants of Pedicularis lasiophrys, along with the four known compounds, verbascoside, cistanoside C, cistanoside D and 8-epiloganin. On the basis of spectral and chemical evidence, pedicularioside E and F were identified to be 1'-O-beta-D-(3-methoxy-4-hydroxy-beta-phenyl)-ethyl-6'-O ...

Iridoid Glycosides of Leonurus persicus

Journal of Natural Products, 1999
Two new iridoid glucosides, 6-O-acetylajugol (1) and 7, 8-epoxy-8-epi-loganic acid (2), together with five known iridoid glucosides, galiridoside (3), ajugoside (4), 10-deoxygeniposidic acid (5), 7-deoxy-8-epi-loganic acid (6), and 8-O-acetylharpagide (7), have been isolated from the aerial parts of Leonurus persicus.

Iridoid glycosides from Thunbergia grandiflora

Phytochemistry, 1996
The novel iridoid glycosides, isounedoside and grandifloric acid, were isolated from Thunbergia grandiflora. Grandifloric acid contains C-10 as a carboxylic acid group, the presence of which was predicted by recent iridoid biosynthesis studies carried out within T. alata. Isounedoside contains a rare 6,7-epoxide functional group.

Iridoid glycosides ofVerbascum laxum

Chemistry of Natural Compounds, 1987
The epigeal part ofVerbascum laxum Filar, et Jav. has yielded in addition to the known sinuatol, a new iridoid glycoside — 6-0-(3″-0-p-coumaroyl-α-L-rhamnopyranosyl)aucubin (I), [α] D 20 −174.2±0.7° (c 1.4; MeOH).

Iridoid glycosides and glycosidic constituents from Eriophyton wallichii Benth

Phytochemistry, 2011
C₉-iridoid glycosides, wallichiisides A-C, and four dimers, wallichiisides D-G, together with 13 known glycosidic compounds, were isolated from whole plants of Eriophyton wallichii Benth. Their structures were elucidated by spectroscopic methods and comparison with literature values.

Iridoid glycosides ofVerbascum saccatum

Chemistry of Natural Compounds, 1983
An aqueous solution of a methanolic extract of the epigeal part ofVerbascum saccatum C. Koch (1.4 kg) was washed with organic solvents and chromatographed on columns of alumina, polyamide, and silica gel, leading to the isolation of 3.6 g of a new iridoid glycoside — saccatoside (I) — in the form of an amorphous substance with [α] D 20 −200±2.5° (c 0.2;
